From the manual for my rear jacks (indicates that there is a fuse and auto reset breaker - I think I found the auto reset breaker in the front compartment of our fifth wheel):
Step 1 - Attach voltmeter (or test light) leads to the motor leads. Does the meter
indicate 12V DC?
If YES, see Step 2; if NO see Step 3.
Step 2 - If YES, at the motor, check the incoming leads to 12V DC (if necessary,
disconnect leads at wire splices). Does meter indicate 12V DC? If YES, motor
needs to be replaced. The motor is not field serviceable. DO NOT ATTEMPT
TO REPAIR. If NO, Inspect all wires and connections between the wall switch
and the motor. Repair connections as necessary. Recheck as in Step 1.
Step 3 - If NO, Inspect all connections between battery and motor. Inspect 6A
Auto-reset Circuit Breaker and 20A Fuse.
Recheck as above in Step 1.
Since there are no field serviceable parts in the motor, electrical troubleshooting
and service is limited to replacing only those components as previously outlined.
Thorough inspection of wiring and connections is the only other electricalservice that can be performed.
